Abstract
A current supply arrangement (A, B) for rectifying three-phase current into multi-pulse DC current with at least one three-phase AC current transformer with a transformer core or three single-phase AC current transformers, each having a transformer core, wherein the three-phase AC current transformer includes three first secondary-side coils (L, L, L), each of which is arranged on a corresponding leg of the transformer core, wherein each secondary side coil is arranged on a leg of the transformer cores, with at least one first rectifier having first converter valves (D, D, D). The first converter valves (D, D, D) are connected with the first secondary-side coils (L, L, L) to form the first rectifier, wherein the current supply arrangement (A, B) includes means (S, S, S) for changing the transformer ratio of the three-phase AC current transformer or the transformer ratios of the three single-phase AC current transformers.
